Error description
DS1TRBAL is not set correctly by DFSMSdss COPY processing when a multi volume single striped extended format sequential V2 data set is copied with Fastreplication / Flashcopy. This occurs whenever the last used track number for the extents on a target volume is larger than x'FFFF' (d'65535') tracks. The COPY process itself completes with RC0 CC0, but the target data set is corrupted. Note: For extended format data sets, the last used track and block on track is indicated by F1-DSCB fields DS1LSTAR & DS1TRBAL. DS1TRBAL contains the high order two bytes (TT) and DS1LSTAR contains the low order two bytes (TT) of the four-byte last used track number.
Local fix
specify DSS COPY keyword FR(NONE). Note: NONE specifies that fast replication should not be used.
Problem summary
**************************************************************** * USERS AFFECTED: All DFSMSdss users performing logical COPY * * of single striped multi-volume version 2 * * extended format sequential data sets. * **************************************************************** * PROBLEM DESCRIPTION: When performing a DFSMSdss logical * * COPY, the DS1TRBAL may not be updated * * correctly for single striped multi * * volume extended format sequential * * version 2 data set after using * * fast replication ( Flashcopy ). * * * * When the data set is copied using fast * * replication and the target data set * * exceeded 65,535 tracks on a single * * volume, the data beyond the DS1LSTAR * * may not be accessible. * **************************************************************** * RECOMMENDATION: * ****************************************************************
Problem conclusion
Fast replication of single striped multi volume extended format sequential version 2 data sets will be disabled. It will later be enabled with APAR OA48754. If an attempt is made to process such data sets DFSMSdss will process the data set using a utility and prevent the use of fast replication. If FASTREPLICATION(REQUIRED) is specified ADR938E will be issued and the copy will fail. KEYWORDS: FLASHCPY/K
